DURABILITY ON-DEMAND.

INTRODUCING A COMPLETE LINE OF ON-DEMAND
GAS-FIRED WATER HEATERS.

STATE ON-DEMAND
GAS WATER HEATERS.

The durability of State.
The convenience of continuous flow delivery.

On-demand, or tankless, technology is not
new. It’s been in existence for about 30 years
in other parts of the world. Now State com­bines this efficient technology with our rep­utation for durability and rugged perform­ance to bring a line of residential and com­mercial tankless heaters to America.

State’s on-demand water heaters use a
high-fire burner to quickly raise the tem­perature of water passing through a cop­per heat exchanger. Only after the heater
senses the demand for hot water does the
burner initiate its ignition sequence,
ignite and begin to heat the flow of water.

All State on-demand heaters are gas-fired.
And because the burner is not ignited
until there is a demand for hot water,
they’re highly energy efficient.

Remember: on-demand water heaters are
designed for specific usage situations.
Consult your sales rep or contact State at
800-365-0024 for specifications and recom­mendations regarding all State storage and
on-demand product applications.

MODEL SELECTION GUIDE.

Ground water
temperature factor.

The temperature of incoming ground
water (cold water inlet temperature)
varies greatly throughout the U.S. and
also fluctuates with change of season.
The temperature of water as it enters the
water heater will determine the amount
of “temperature rise” required to achieve
the desired hot water outlet temperature
(120°F is recommended).

The best way to measure your incoming
ground water temperature is to use a
thermometer to measure cold water tem­perature during the coldest season
of the year. To simplify the process, use
this map to determine whether your
installation location is in the Southern
Zone, Central Zone or Northern Zone.

Average Ground Water Temperatures

SOUTHERN ZONE

Average Ground Water

Temperature: 62°F to 77°F

CENTRAL ZONE

Average Ground Water

Temperature: 52°F to 61°F

NORTHERN ZONE

Average Ground Water

Temperature: 37°F to 51°F

Peak hot water demand.

The next step is to determine how much
hot water will be required during its
busiest usage period (“peak demand”).
To use the chart, consider all appliances
and fixtures that use hot water, including
lavatory faucets, kitchen faucets, washing
machines, dishwashers, showers and bath­tubs. Be sure to determine how
many appliances and fixtures will be used
at the same time during peak demand.
